Complete the Field in Cisco DNA Center for Network Discovery

D.

When initiating a network discovery in Cisco DNA Center, the field that must be completed is the "Discovery Type."

Discovery Type refers to the specific type of device discovery that is being performed, such as a "Discovery with Credentials" or "Discovery with SNMP." This setting determines the authentication method used to access and identify network devices during the discovery process.

In a "Discovery with Credentials" type, the discovery process will use the device's credentials to access it, while in a "Discovery with SNMP," the Simple Network Management Protocol (SNMP) is used to gather information about the device.

It's worth noting that the other options listed in the question are also important fields that may need to be completed depending on the specific network environment and the type of discovery being performed. For example, the SNMP read community string may need to be entered when using SNMP for device discovery, while the Enable password may be required for device authentication during a "Discovery with Credentials" type of discovery. The NETCONF port may also be relevant when using NETCONF as a protocol for device discovery.

However, in general, the "Discovery Type" field is the most critical field that must be completed when initiating a network discovery in Cisco DNA Center, as it sets the stage for the entire discovery process.
